What Ember does

Eight quiet superpowers, one calm window.

Ignite AI, your private co-author

Draft, rewrite, brainstorm, and find sources without ever leaving your manuscript. Suggestions stream inline; nothing is uploaded, indexed, or trained on.

Learns your voice, not your data

Ember studies the prose inside each project on-device, so Ignite's suggestions match your rhythm and word choice, and that knowledge never leaves your Mac.

Built on Apple Intelligence

Native integration with Apple Intelligence on supported Macs means fast, local generation that respects the platform you already trust.

Privacy by construction

Local-first by default. No telemetry on your writing, no cloud sync of drafts, no third-party model providers reading your words.

Source-grounded research

Look things up without breaking flow. Ember surfaces citations and quotes you can drop in, with the source link kept right beside them.

Made for long-form

Project-level outlines, chapter views, and a reading mode tuned for the cadence of essayists, Substackers, and novelists.

Proofread that respects your voice

Catch typos and tighten sentences without flattening your style. Every change is a suggestion you can accept, refine, or wave off.

Keyboard-first

Every action lives behind a shortcut. Ignite, Proofread, and navigation are all one chord away. No menu hunting in the middle of a sentence.

A closer look

Built around the page, not the chatbot.
